This specialized tap allows for precise restoration of the sensor mounting hole, preventing costly NOX sensor replacements due to compromised threads. Its design focuses on accuracy and efficiency, ensuring a reliable repair.

Key Features

  • Integrated Guide Pin: Features an integrated guide pin designed to prevent angled entry, ensuring the tap precisely follows the existing thread path and protects the sensitive NOX sensor.
  • M18 x 1.5 Thread Size: Specifically engineered for the common M18 x 1.5 thread found in numerous NOX sensor applications, guaranteeing compatibility and effective repair.
  • Cost-Effective Repair: Enables technicians to repair damaged threads rather than replacing an entire, expensive NOX sensor, significantly reducing repair costs for customers.
  • Durable Construction: Manufactured by Mueller-Kueps, known for professional-grade automotive tools, ensuring durability and reliability in demanding workshop environments.
  • Prevents Further Damage: By facilitating a straight and accurate re-tapping process, this tool helps prevent cross-threading and further damage to the exhaust system components.

Applications

This Sensor Tap is ideal for use in professional automotive and industrial settings where vehicles, particularly those with diesel engines, require maintenance or repair of their emissions systems. It is commonly used when:

  • Removing a NOX sensor has caused damage to the sensor port threads in the exhaust system.
  • A NOX sensor needs to be reinstalled, and the existing threads are corroded or compromised, preventing proper seating.
  • Preventative maintenance requires cleaning or refreshing the threads before installing a new sensor.

This tool provides a reliable solution for maintaining the integrity of critical exhaust system components, ensuring proper function and fitment of NOX sensors.
